How old is too old?

I had a Marantz SA7 S1 SACD/CD player that was excellent... until the mechanical drive quit.  Nobody wanted to fix it... not sure any parts were available.  The new version of the Marantz SA10 series was about $14K as I recall.  Just too expensive as I stream Qobuz and Tidal with Roon using a dCS Bartok.  But, how to play my SACD collection?  I decided on a new Marantz 30N.  It will play my CDs as a turntable outputting to the Bartok by 75 Ohm cable.  With the Bartok as a DAC I have excellent sound.  But of course, no SACD output.  But SACD digital conversion is much easier and less complicated process than PCM. And the Japanese folks put good SACD DACs in their stuff so I just let the Marantz do the work for those disks with excellent sounding results into my analog preamp.  A reasonable compromise to money and sound but not much of one, if any, to  sound quality.

Come on man ,you should know that buying used audio equipment is a crazy shoot....I know it after getting burned a number of times...

I just purchased for a pittance fantastic full range, rosewood finished 30 year old tower speakers, the Legacy Signature IIIs.  It sounds just like my black versions now residing next to my 85" 4K TV (my wife loves it powered by 1978 Yamaha CR 620 receiver).  I never purchased used cartridges, tonearm or turntable.  Purchased used R2R machines, amps, pre-amps, receivers, phono-pre amp (EAR 324) receivers and speakers (especially speakers) due to price.  Selling older used equipment is more difficult and now more difficult (forget Ebay-maybe for purchasing only as it is a buyer's world with the seller more likely to get suckered by the buyer).
